Vanilla Custard Cream Squares are a timeless dessert that perfectly balances textures and flavors. A buttery graham cracker crust forms the base for a rich, velvety vanilla custard filling, creating a dessert that is both comforting and elegant. Each bite delivers a satisfying contrast between the crisp crust and the smooth, creamy custard.
Infused with pure vanilla, the custard has a warm, aromatic depth that pairs beautifully with the lightly sweet graham cracker base. These squares are ideal for gatherings, holidays, or a simple homemade treat. Serve them chilled for a refreshing finish or at room temperature for a softer, creamier bite.
Ingredients
For the Crust
-
1½ cups graham cracker crumbs
-
⅓ cup butter, melted
-
¼ cup granulated sugar
For the Custard
-
2 cups whole milk
-
1 cup heavy cream
-
¾ cup granulated sugar
-
5 large egg yolks
-
3 tablespoons cornstarch
-
2 teaspoons vanilla extract
Instructions
Step 1: Prepare the Crust
In a medium bowl, combine the graham cracker crumbs, melted butter, and sugar. Mix until evenly moistened.
Press the mixture firmly into the bottom of a parchment-lined or lightly greased baking dish, creating an even layer. Place in the refrigerator to chill while preparing the custard.
Step 2: Heat the Milk Mixture
In a saucepan set over medium heat, combine the whole milk and heavy cream. Heat until steaming, but do not allow it to boil. Remove from heat once small bubbles appear around the edges.
Step 3: Prepare the Egg Mixture
In a separate bowl, whisk together the egg yolks, sugar, cornstarch, and vanilla extract until smooth and well combined.
Step 4: Temper the Eggs
Slowly pour the hot milk mixture into the egg mixture, whisking constantly to prevent curdling.
Once fully combined, pour the mixture back into the saucepan.
Step 5: Cook the Custard
Return the saucepan to medium-low heat. Cook, stirring constantly, until the custard thickens and coats the back of a spoon. This should take about 5–8 minutes. Do not let the custard boil.
Step 6: Assemble
Pour the hot custard evenly over the chilled crust. Smooth the top with a spatula.
Step 7: Chill and Set
Refrigerate for at least 4 hours, or until fully set. For best results, chill overnight.
Step 8: Slice and Serve
Once set, cut into squares and serve chilled or at room temperature.
